How To Place A Grounding Rod

By Martha White


It is important to have your house or permanent structure properly grounded if you have electricity in the building. This can help prevent a fire should lightning strike or some other electrical surge be sent towards the building. Installing a grounding rod properly is very important but also much easier than you might think. There are some regulations in areas on what the requirements are, so be sure to check and see what the rules are in your area. You will also want to ask your utility company to mark where any underground lines are so you avoid hitting them when installing the rod.

First, you need to gather the equipment needed. This will include a shovel or post hole digger, a driving tool, hammer or mallet, and the proper type of rod. They are eight feet long and usually made of copper. Ask your hardware store to point you to the right type of rods for the job. Using the wrong material will not protect your home from a surge.

The next step is to dig the hole. Avoid rocky areas or any places that the utility company marked for other lines. The spot you pick should be between one and two feet from the building for it to work the best. If it is too close, it can reduce the effectiveness by putting the surge back into the building.

With the spot selected you can begin to dig. If you have a post hole digger, you can dig a couple of feet down easily. Using a shovel is fine, but you do not need to dig a wide hole. Dig the hole as deep as you can before moving to the next step.

When the hole is dug, add water. This is to help soften the ground so it will be easier to push the pole into the ground. Being by pushing it by hand. You may have to move it around in a circle to help get it through the packed dirt. There will be one end that is pointed and that one should go into the ground. At some point, you won't be able to hand push it in and will need to move to the next step with the tools.

After you have the rod a couple of feet into the ground, start hammering. There will be a point where it just won't go in manually anymore. If you do not have a driver, which is placed over the top of the rod allowing you to easily drive it in, you can put a board over it to make a bigger surface to hit. Keep hammering and driving it until there is just an inch or two sticking above the top of the hole.

Now you want to attach a ground wire. This will also be attached to your electrical panel, so be sure to handle with care. Some are shielded wires, so you will need to cut the end and expose the copper wire. Use a special clamp to connect to the pole. Make sure there is enough slack in the wire that bumping it will not disconnect it from the rod. You may want to dig a small trench to bury the wire it if is in an area that will be mowed and away from the house a few feet.

The last step is to fill in the hole. If you have it completely under the ground or exposed by an inch or so, pack the dirt in so it will be protected. Make sure it is low enough that a lawn mower will not hit it with the blades.
